Market report: Monday close

Could the bear run in shares of BP be about to come to an end? That was the question being posed by investors after one of the City's big guns changed its recommendation on the shares ahead of tomorrow's full-year results.

US broking house Goldman Sachs, which has been lukewarm on BP for some time, dramatically changed its recommendation on the oil giant from neutral to buy just hours before outgoing chairman Lord Browne unveils final trading numbers.

Goldman says the de-rating of BP, up 6½p today at 541½p on turnover of 43m shares, had been 'severe', with the shares having collapsed 25% since last April when the price reached 1714p. The fatal explosion at its Texas City refinery in 2005 combined with leakage last year at the Prudhoe Bay pipeline and its subsequent partial closure dented BP's image globally and caused much of the sell-off in the shares.

Goldman has told clients it expects tomorrow's results to be a potential catalyst despite the high probability of lower guidance targets as the outlook for 2007-8 improves. Its target price of 615p offers about 14% potential upside, second only to Italian rival ENI in the European sector.

Today's move by Goldman was taken against the backdrop of a rise in the oil price overnight. The global crude future rose more than $1.50 to $58.80 a barrel but eased slightly today.

Shares generally traded in a narrow range at the start week. A poor finish in New York on Friday and mixed trading in Asia today offered little incentive to City investors. The FTSE 100 index was 7 points ahead at 6317.9 in thin trading.

Star performer among blue-chips was Johnson Matthey, which was squeezed 91p higher to 1583p after being raised from neutral to buy and having its price target jacked up from 1490p to 1800p by UBS. The metallurgist has performed poorly of late but is now the Swiss broker's preferred pick of the chemicals sector. UBS says earnings are set to grow strongly over the next five years, and forecasts compound growth of 13% a year.

Man Group, the UK's largest hedge fund operator, was another star turn, adding 24p to 570¾p. Credit Suisse has repeated its outperform rating on the shares and raised its target from 570p to 630p following weekend reports that the group is planning a US listing for its shares. The broker points out that Man's funds have provided robust returns in recent months.

Traders reported another day of hectic turnover in J Sainsbury following last week's flurry of excitement. The price firmed a further 2½p to 509½p with more than 50m shares changing hands as speculators awaited fresh developments.

On Friday, a consortium of private equity companies including CVC, Blackstone and Kohlberg Kravis Roberts-expressed an interest in bidding for the supermarkets chain, which is still controlled by the Sainsbury family. Rumours today suggested Marks & Spencer, down 11p at 706½p, may throw its hat into the ring if it can gain the family's support.

Many in the City cannot see any offer from the private-equity consortium getting off the ground. It would have to bid at least 600p a share, which would value the company at more than £10bn.

Monterrico Minerals stood out with a jump of 68½p to 366p after agreeing a 350p offer from Chinese outfit Zijin Mining that values the business at £94.6m.

Analyst Charles Kernot of broker Seymour Pierce continues to rate the shares outperform with a target of 486p - way above the terms. He reckons a counterbid could be in the offing, and points out the offer came in tandem with details of Monterrico's Rio Blanco feasibility study.

No discounted cashflow valuation was provided in the study, which would show how low the offer is in comparison with the potential value of the project.
